Defines HTML in the right corner of the toolbar.

<div class="definition">
    Array of strings, default = ['']
</div>

You can define a custom HTML to appear in the right corner of the toolbar if you set <span class="argument">.right</span> property.
If it is a single string, it will be converted to an single cell array. You can render buttons
in the right corner of the toolbar if you add a toolbar item of <span class="argument">type</span> = spacer.
If you add a spacer, all of the toolbar items that follow will be aligned to the right, but right text will still be on the right
from them.

In case of multi line toolbar (see <a href="http://w2ui.com/web/demos/#/toolbar/11">demo</a>), you can
define <span class="argument">.right</span> property as an array of strings.

You can defined it during object creation:
<textarea class="javascript">
let toolbar = new w2toolbar({
    name  : 'toolbar',
    right : 'text on the right',
    items : [
        { type: 'check',  id: 'item1', text: 'Check', icon: 'icon-page', checked: true },
        { type: 'radio',  id: 'item3',  group: '1', text: 'Radio 1', icon: 'icon-add' },
        { type: 'radio',  id: 'item4',  group: '1', text: 'Radio 2', icon: 'icon-add' }
    ]
});
</textarea>

Or any time during run-time:
<textarea class="javascript">
w2ui.toolbar.right = ['text on the right']
w2ui.toolbar.refresh()
</textarea>
